autologic Posted September 25, 2006 Share Posted September 25, 2006 Hello everybody. My system is a ThinkPad T43, ATI X300 Mobility. When I run OS X 10.4.6 off of AC power, the video and everything else runs flawless. But - when I boot the computer off battery power, OS X video runs at about 1/2 speed! Not choppy, but in slow motion. Also, if I boot off AC, let OS X boot, then disconnect from power, everything runs fine. What's wrong? Thanks in advance, autologic Link to comment Share on other sites More sharing options...
Bruce Wang Posted September 25, 2006 Share Posted September 25, 2006 I read somewhere in the forum, you can disable SpeedStep in BIOS. Search "throttle" in the forum for related information. Bruce Link to comment Share on other sites More sharing options...
autologic Posted September 25, 2006 Author Share Posted September 25, 2006 thanks bruce! i updated my thinkpad bios - what an update! there were new settings for just about everything, including speedstep options for both power and battery that weren't there before. thinkpad owners - update your BIOS if you have my problem!
